Find the second, fourth, and eleventh terms of the sequence described by the rule.
A(n)= 8+ (n 1)(12)
A(2)=
(Simplify your answer. Type an integer or a decimal.)

Given that the nth rule for the sequence is

We need to determine the seconds, fourth and eleventh terms of the sequence.

Second term:

The second term of the sequence can be determined by substituting n = 2, in

Thus, we have;

Simplifying, we get;

Thus, the second term of the sequence is 20.

Fourth term:

The fourth term of the sequence can be determined by substituting n = 4 in

Thus, we have;

Simplifying, we get;

Thus, the fourth term of the sequence is 44.

Eleventh term:

The eleventh term of the sequence can be determined by substituting n = 11  in

Thus, we have;

Simplifying, we get;

Thus, the eleventh term of the sequence is 128.
